RAILWAX-FREIGHT-GAR END WALL.

Application filed October 13, 1924. Serial No. 743,343.

In the manufacture of railway freight cars it is desirable and economical to have as few parts as possible so as to simplify and expedite the assembly of these parts into a completed car. It is laborious, eX- pensive and slow to make numerous and sundry parts, especially when they must be made in various types of manufacturing plants, such as foundries, shearing departments, pressing departments and riveting departments, and then all such part-s shipped to the assembling department.

My invention has for its object the formation of a number of the usual and standard parts of a freight car from one piece of steel plate so that it can easily be formed, shipped and readily applied to the remainder of the car.

In the drawings:

Fig. 1 shows an end wall of a railway freight car made of a single steel plate, comprising numerous parts, which were formerly made separately.

Fig. 2 is a rear view of a portion of Fig. 1 showing the coupler opening the lower flange and attachment of the center sill to the body of the plate.

The metallic plate 1 (preferably steel) has the reinforcing corrugations 2 integrally formed therein, which may be of any de sired contour. The push pole pockets 3 are also integrally formed therein of any desired form. The top edge of the plate is bent back upon itself (4) and preferably secured thereto by rivets 5 only one of which is indicated to form a hollow box girder or beam between the side walls6 of the car. The ends of the beam, or top chord, 7 are secured to the side top chords 8 in any convenient manner, for instance, by the gussets 9.

The plate has a flange 10 on the side vertical edges which is secured to the side wall 11 by rivets 12 and to the top side chord 8 by rivets 13 so that it is a beam between these two longitudinal frame members, and, furthermore, the side flanges are wider at the bottom where they are secured to the side sills 11 so that the flange is a vertical beam supported at oneend to resist the tendency of the side wall to shift longitudinally and also to support the ends of the corrugations 2. In other words, the integral flange performs the functions of the usual corner posts.

The plate has a flange 14 at the bottom edge which is secured to the side sills 11 and center sills 15 (by gusset 20) to unite hese longitudinal underframe members and otherwise perform the usual functions of the end sill.

An opening 16 is provided near the bottom of the plate, but above the bottom flange 14, as it is preferable to have this flange extend continuously from side sill -(11) to side sill. The center sills 15 are positioned on either side of this opening 16 and are clipped to the end wall by rivets 17. The coupler is inserted through this opening and then attached to the draft rigging.- The opening is provided with an inturned flange 18 on its bottom edge to support the coupler and with flanges 19 on its side edges which are prefcrably secured to the center sills by rivets 21. The opening 16 is also provided with an upper flange 22.

I claim:

1. An end wall for a railway car formed 7 from a flat metallic plate with reinforcing corrugations, push pole pockets, top chord all formed integral therewith, with an integral bottom flange and integral side flanges to perform the functions of the usual end sill and corner post respectively,

and an opening above said bottom flange ffor insertion of a coupler.

2. 'An end wall for a railway car formed from a flat metallic plate with reinforcing corrugations, push pole pockets, top chord all I formed integral therewith, with an integral bottom flange and integral side flanges to perform, the functions of the usual end sill and corner post respectively, and an openin above said bottom flange for insertion of a coupler provided with an inturned 1 ARTHUR E.
